    Further bus nodes for diagnostic devices can be connected to the integrated PG female connector. Only CAT5-TCP cables with an RJ45 connector can be connected to the NETLink S7-Compact housing. No further outlets, for example, PROFIBUS cable, can be installed on the device. Therefore no termination is possible on the connector housing and the ON/OFF switch for this is not been incorporated.

    PC via TCP/IP. Installation of the driver software The NETLink S7-Compact is inserted in the PG/PC interface of an existing Simatic application and can then be used from most Simatic engineering tools (STEP7, ProTool, WinCC, etc.). Access is possible to any controllers of the Simatic S7-200, S7-300, or S7-400 series via a NETLink S7- Compact.
  • Page 16 NETLink S7-Compact - User Guide This opens the Install/uninstall interface dialog box. After you have selected the entry NETLink-S7-NET PRO family from the left-hand list, click the [Install-->] button. The NETLink-S7-NET PRO has now been included in the selection list so that it is available for selection in future.

  • Page 17: Selecting The Required Interface Parameterization

    The selection list for the interface parameter sets now contains an additional three items for NETLink®. All relevant settings of a NETLink S7-Compact driver can be made via the [Properties] access field. With the button [Diagnostics...] it is possible to show the nodes connected to the bus and the parameters the bus is working with.

  • Page 18: Configuration

    5.1.1 Setting the IP address of your PC Before you can operate the connected NETLink S7-Compact you will have to change the default IP address of the NETLink S7-Compact so that your PC can communicate with the device. The following steps apply to Windows 10:...
  • Page 19 Select Use the following IP address and enter a specific IP address and Subnet mask. Note NETLink S7-Compact is supplied with the IP address 192.168.4.49. This means that you will have to use the same address range for your computer.

  • Page 20: Bus Settings

    The bus configuration is passed to the NETLink S7-Compact during the runtime of the NETLink S7- Compact driver and is not stored in the device.

  • Page 21: Profibus Configuration

    The network settings can be adapted manually if the checkmark next to Automatic Baud Rate Detection is removed. This is usually only necessary if the NETLink S7-Compact fails to sign onto the bus system automatically (can happen with passive bus participant).
  • Page 22 NETLink S7-Compact - User Guide In this case, the timeout value should be increased correspondingly. Profile: § Under PROFIBUS, there are usually the profiles DP, Standard und User defined. § The profile must be selected that is already used in the programmable controller.
  • Page 23 Chapter 5 - Configuration Under PROFIBUS, please note that the auto baud function works best if the Cyclic distribution of the bus parameters function is activated in the programmable controller used. Note Note regarding the Ttr (Target Token Rotation Time) parameter: Make sure that the value for the Ttr parameter is not too small.

  • Page 26 NETLink S7-Compact - User Guide To able to access a NETLink S7-Compact with the NETLink S7-Compact driver, a station must be set up first. This station is virtually and is not stored in the NETLink S7-Compact Gateway hardware – it permits easier differentiation if several NETLink S7-Compact devices are used.
  • Page 27 If you do not want the name that is stored in the NETLink S7-Compact to be the same as the station name, you can overwrite the station name (e.g. replacing the name Softing_test with the name Workshop in the example below).

    Operation without the DHCP If a NETLink S7-Compact is used in a network without a DHCP server (or you want the NETLink S7- Compact to work with the same IP address on the network despite the presence of a DHCP server) the required IP parameters are stored in the input forms for Static parameters.

  • Page 30: Additional Features

    IP address from the DHCP every time it is switched on. The system administrator responsible for the DHCP server can counter this informing the DHCP server of the MAC address of the NETLink S7-Compact device. However, this is additional work for the system administrator.

  • Page 36: Rfc1006-Function (S7-Tcp/Ip)

    Because many visualization system manufacturers have implemented this protocol to implement connections with CPs from Siemens (e.g. CP343 or CP443), a NETLink S7-Compact with RFC1006 is an alternative to communication with these visualization systems. The RFC1006 functionality of the NETLink S7-Compact Gateway is also supported by S7-200 systems.

    NETLink S7-Compact unit. To use this feature, you will have to enter the rack and slot numbers for the target address into the relevant RFC 1006 driver on the SCADA/HMI application you are using.
  • Page 38 NETLink S7-Compact - User Guide Section Address conversion table includes a table that shows addresses converted into rack and slot values. There are many parameter configuration tools that do not have fields with the names Rack and Slot. Instead, these tools usually have an input field called Remote TSAP that is two bytes long and needs a hex format value.

  • Page 39: Bus Parameters In Single Master Operation

    Bus parameters in Single Master Operation If the NETLink S7-Compact Gateway is connected to a bus system on which no other master is active, the NETLink S7-Compact generates the token itself. This feature can be enabled on the web interface under Basic Configuration.
